Title: Optical disc apparatus
Inventor: TAKEDA NAOTO
IPC: G11B7/09
Filed: 2002-03-25
Granted: 2003-11-21
Abstract: Four address information ID1 to ID4 are formed on a head portion of an optical disc, such as a DVD-RAM. The mode determining device 30 determines whether the addition signal or the subtract signal from the signal processing device 22 that signals are two-divided in the radius direction is to be used for reproducing the address information. Afterwards, the signals are transmitted to the controller 20. When there is a focusing deviation, the addition signal is used for reproducing the address information, and when there is a tilt, the subtract signal is used for reproducing the address information. In addition, the addition or the subtract signal that has larger address number is used for reproducing the address information. Therefore, the optical drive, such as the DVD-RAM drive, can exactly reproduce the address information formed on the head portion.

Abstract: The present invention provides a method for forming a desired plating film on a desired place at a reasonable cost. When workpieces are mixed in a plating solution containing Ni ions with a great number of Zn particles having an average diameter of 1 mm and having an electrochemically base immersion potential with respect to the precipitation potential of Ni, the Zn particles are dissolved and generates electrons, the potential of Cu electrodes in contact with the Zn particles is shifted to an electrochemically base potential side, and hence the Ni ions are precipitated on the electrodes, thereby forming Ni plating films on the surfaces of the electrodes. In a manner equivalent to the above, when Zn particles are immersed in a plating solution containing Sn ions, the Zn particles are dissolved and generates electrons, the potential of the Ni plating films in contact with the Zn particles is shifted to an electrochemically base potential side, and hence the Sn ions are precipitated on the Ni plating films, thereby forming Sn plating films.
